Description
Vari-Speed Laminar Flow Hood 40x39x24 120V Variable Speed HEPA Needs Wiring
This Vari-Speed horizontal laminar flow hood is a bench-style clean air workstation designed to deliver a continuous stream of HEPA-filtered air across the work surface, maintaining a particle-free environment for sensitive processes. The unit measures 40" W x 39" D x 24" H and runs on standard 120V AC power. It is equipped with a solid-state variable speed controller (Vari-Speed brand) that adjusts fan output. This unit is being sold as-is for parts or repair — it requires wiring completion, a replacement pre-filter, and new light bulbs and switch before it can be put into full service.

Applications
Laminar flow hoods are standard equipment in cleanroom and controlled-environment settings where airborne particle contamination must be minimized. Horizontal laminar flow benches like this one push HEPA-filtered air in a smooth, unidirectional stream from the rear filter bank toward the operator, keeping the work zone swept clean of particulates. They are widely used in semiconductor fabrication, microelectronics assembly, pharmaceutical compounding, laboratory sample preparation, and optical component handling — anywhere that particle contamination can damage product or compromise results. A variable speed blower allows the airflow velocity to be tuned to the application, balancing filtration effectiveness with operator comfort. Units of this type and size are suitable for benchtop or floor-standing deployment in a dedicated cleanroom bay or as a standalone clean work area. A buyer with wiring, filtration, and lighting skills can restore this unit to service at a fraction of the cost of a new comparable hood.
This Vari-Speed Laminar Flow Hood is being sold as-is for parts or repair. The fan/blower runs and directs airflow toward the work surface, and the variable speed control functions. The light fixtures could not be tested — the bulbs and light switch need to be replaced. The unit also needs wiring completed (the top-mounted junction box has bare wire ends not yet terminated) and requires a new pre-filter; the existing HEPA filter media shows visible damage with torn and crumpled sections. The cabinet exterior shows paint chipping and wear on the edges and corners consistent with shop use. The unit is on a pallet and appears structurally intact.
